dc.description.abstract | El trabajo final de maestría que aquí se presenta es una revisión de literatura de los avances en la extracción de metales mediante el uso de plantas, tema que ha tomado relevancia actualmente dado el principio de sostenibilidad en el cual está enmarcado. Esta tecnología usa la capacidad de algunas plantas de acumular metales para dar origen a “bio-menas” que además de remediar ambientes contaminados inmovilizando o capturando contaminantes, podría generar un beneficio económico adicional mediante la extracción y posterior comercialización de los metales asimilados. Así como la minería involucra diversos procesos para lograr la recuperación de los diferentes metales, la fitominería involucra especies particulares de plantas con la capacidad de acumular altas concentraciones de metales y generar biomasa que puede ser incluida en varias etapas del ciclo minero, por ejemplo como herramienta para la ubicación de objetivos en exploración, extracción de elementos con valor económico y en la mitigación de impactos por contaminación en el cierre de minas o remediación de pasivos ambientales. Este trabajo pretende mostrar las ventajas de los desarrollos de esta aplicación en los procesos de mayor relevancia dentro del ciclo minero e incentivar la investigación a nivel nacional, ya que existen problemas reales de contaminación como pasivos ambientales en pequeña minería metálica, presencia de metales pesados en fuentes hídricas, productos de un crecimiento industrial y poblacional desordenado, que aportan al medio ambiente metales tales como, cadmio, mercurio, plomo y arsénico los cuales podrían ser tóxicos para los organismos vivientes y requieren ser controlados. De igual forma se aportan otros iones metálicos como Ni, Au, Ag, Mn, Cu entre otros, los cuales pueden tener un aprovechamiento económico con el uso de esta tecnología, además, esta tecnología toma relevancia ya que es posible la existencia de las plantas identificadas por los autores estudiados con especies endémicas en el país, con lo cual es posible diseñar proyectos de interés económico con la aplicación de técnicas de fito-extracción y fito-estabilización del cual se presenta un caso de estudio. | spa |
dc.description.abstract | The final master’s degree paper presented here is a literature review of the advances in the extraction of metals through the use of plants, a topic that has now taken on relevance given the principle of sustainability in which it is framed. This technology uses the capacity of some plants to accumulate metals to give rise to "bio-ores" that in addition to remediating contaminated environments by immobilizing or capturing pollutants, could generate additional economic benefit through the extraction and subsequent marketing of the assimilated metals. Just as mining involves various processes to achieve the recovery of different metals, plant health involves particular plant species with the ability to accumulate high concentrations of metals and to generate biomass that can be included in several stages of the mining cycle, for example as a tool for locating targets under exploration, extraction of elements with economic value and in mitigation of pollution impacts in the closure of mines or remediation of environmental liabilities. This paper aims to show the advantages of the developments of this application in the most relevant processes within the mining cycle and to encourage research at national level, because there are real problems of pollution such as environmental liabilities in small metal mining, presence of heavy metals in water sources products of a disorderly industrial and population growth, which provide the environment with metals such as cadmium, mercury, lead and arsenic to be toxic to living organisms and need to be controlled. Other metal ions, such as Ni, Au, Ag, Mn, Cu, among others, which can be used economically with the application of this technology, in addition, this technology takes on relevance since it is possible the existence of the plants identified by the authors studied with endemic species in the country, with which it is possible to design projects of economic interest with the application of phyto-extraction and phyto-stabilization techniques, of which a case study is presented. | eng |
